Specification of Letters Patent.

Patented Nov. 16, 1915.

Application filed August 10, 1914. Serial No. 856,057.

To all whom it may concern Be it known that I, JOHN J. CRoUsn, a citizen of the United States, residing at lrVaterbury, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Fuse-Carriers; and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear,

and exact description of the same, and Which-said drawings constitute part of this application, and represent in Figure 1 a top view of a switch-block showing one fuse-carrier in connection therewith. Fig. 2 an end view partly in section of the same. Fig. 3 a side view partially in section. Fig. 4 a side view of the fuse-carrier detached. Fig. 5 an underside view of the same. Fig. 6 an enlarged end view of one of the fuse fingers, detached.

Fig. 7 a sectional view of the same showing one end of the fuse connected therewith.

This invention relates to an improvement in fuse-carriers adapted for use in connec position or removing the fuse, the possibility of injury to the operator is avoided.

Another object of the invention is to provide a fuse-holder which is limited to certain amperage of fuse and so as to prevent the use of a fuse of higher predetermined amperage; and the invention consists in certain details of construction and combinations of parts as will be hereinafter described and particularly recited in the claims.

In illustrating my invention I have shown it applied to a fuse-block 2 of substantially usual construction, but it will be clearly understood without further illustration that 5 it might readily be used in connection with terminals secured to a switch-board or panel. As herein shown, the fuse-block 2 is a double block provided with terminals 3, 4, each in electrical contact. with a pair of 5 spring-fingers 5, 6. The fuse-carrier 7 is made of insulating material and is formed on opposite sides with downwardly projecting guards 8, 9, and preferably formed on opposite sides with finger-recesses 10 by the holder may be conveniently gripped. The interior of this fuse-carrier may be provided with an asbestos lining 11 and supports two downwardly projecting fuse fingers 12, 13, firmly secured to the carrier adapted to enter between the terminal clips 5 and 6. In the base of each of the fingers 12, 13, is atransverse slot 14 through which a ribbon fuse 15 may be passed. The length and width of these slots determine the size of the fuse to be employed, and so that a fuse greater in width or thickness than is suitable for the determined amperage for the circuit cannot be inserted, although any fuse of lower amperage may be used. The ends of the fuse are folded around the rounded ends of the fingers 12 and 13 and so that when these fingers with the ends of the fuse folded around them are pressed inward, they make a firm contact with the terminal clips 5 and 6 and so as to close a circuit between the terminals 3 and 4:. By folding the ends of the fuse around the fingers the greatest resistance is at the fingers and so that in case the fuse does burn out it will burn in the center of the block where it is least liable to do any damage. may be formed as shown in Fig. 7 by applylng sections 16 of a round rod to the ends of the fingers. By thus practically inclosing the fuse the fuse-carrier can be put in place without danger of the fingers of the operator coming in contact with the terminals and the fuse-carrier is readily removable for inspection or replacement of a fuse.

I claim 1. In combination: two cooperating contact members, two fingers carried by one member and terminating in rounded ends and provided with transverse slots of predetermined dimensions, and a ribbon fuse adapted to be drawn through said slots and folded over the rounded terminals of the fingers.

2. In combination: two cooperating contact members, a pair of terminal clips provided on one of said members, a pair of fuse fingers provided on the other of said members and each of which fingers is provided with a' fuse opening of predetermined dimensions, and a fuse drawn through said openings and folded over said fingers, which latter are adapted to engage the corresponding terminal clips of the other member to securely lock the fuse and insure a positive contact thereof with the said clips.

3. The combination with terminal clips,

The rounded ends of the fingerstherein, of a fuse-carrier to fit said channelshaped member, provided with turned-down ends to cover the terminal clips and with lateral guards, extending fingers rigidly secured to said carrier, said fingers each bein 'provided with a fuse opening of predetermined dimensions, and a fuse drawn therethrough and removably held by said fingers,

which latter'are adapted to engage the corresponding terminal clips to lock the fuse f and insure a the said clips.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.

positive contact thereof with JOHN J. CROUSE.
